Abstract
A process for epoxidation of an unsaturated polymer involves mixing an unsaturated polymer and a peroxy acid in an absence of solvent to produce an epoxidized polymer. The process may require no solvent, require no catalyst, require no or little applied external heat input, require no applied cooling, require less epoxidation agent, be faster and/or result in more efficient conversion of the unsaturated polymer.
